I've seen this guy at various social events around DC and I know of the bar. (For the non-DC residents: You need to be on a list to gain admission on the weekend.) Is it possible for both of them to lose?

He was amp'ed up on Red Bull, booze, who knows what else? Also was amp'ed up during the scuffle with his parasympathetic system kicking in. Add all that in with the shock and I could totally see how he didn't notice. Who hasn't gotten into a fight, team sport, etc. and not noticed an injury until after you started to cool down from the intensity?

Not a story I would want published about myself.
